//! @file This file contains adapter code between Bluetopia's GATT APIs and
|
|
//! Pebble's GATT/API code. The functions in this file take the internal
|
|
//! reference types BLECharacteristic and BLEDescriptor to perform operations
|
|
//! upon those remote resources. The implementation uses the functions
|
|
//! gatt_client_characteristic_get_handle_and_connection_id and
|
|
//! gatt_client_descriptor_get_handle_and_connection_id from
|
|
//! gatt_client_accessors.c to look up the Bluetopia ConnectionID and the
|
|
//! ATT handles. These pieces of information is what Bluetopia cares about
|
|
//! when asked to perform a GATT operation.
